Intrusion Detection

Security Onion – platform built by defenders for defenders

Security Onion is a platform built by defenders for defenders. It includes network visibility, host visibility, intrusion detection honeypots, log management, and case management.

Security Onion generates NIDS (Network Intrusion Detection System) alerts by monitoring your network traffic and looking for specific fingerprints and identifiers that match known malicious, anomalous, or otherwise suspicious traffic. This is signature-based detection so you might say that it’s similar to antivirus signatures for the network, but it’s a bit deeper and more flexible than that. NIDS alerts are generated by Suricata.

This is free and open source software.

Features include:

  • Network visibility – collect network events from Zeek, Suricata, and other tools for complete coverage of your network. Cast a wide net to catch the bad guys quickly and easily.
  • Host visibility – supports Elastic Agent for event collection on your organization’s endpoints.
  • Static analysis – import full packet capture files and Windows Event log files for quick static analysis and case studies.
  • Security Onion desktop – use local Linux tools to perform analysis of network and host events.

I’m not keen on Security Onion’s license.
